Major Telecom Network Weaknesses
Telecom networks are not without their flaws, and these vulnerabilities are often exploited by nation-states aiming to compromise infrastructure and gain access to sensitive user data.
Outdated Protocol Security Flaws
Many telecom systems still rely on outdated protocols, which leave them open to exploitation. Legacy systems like SS7 and Diameter are particularly vulnerable, allowing attackers to conduct surveillance, intercept communications, and even track users’ locations. The Department of Homeland Security has highlighted the risks here:
"believes SS7 and Diameter vulnerabilities can be exploited by criminals, terrorists, and nation-state actors/foreign intelligence organizations."
These flaws make it possible for attackers to track users, intercept voice data, and even steal multi-factor authentication (MFA) keys. The issue is especially pronounced in the United States, where telecom networks have grown piecemeal through acquisitions and mergers, leaving many outdated systems in place.
Adding to the complexity, the rapid growth of IoT devices has introduced a whole new set of security challenges.
IoT Security Gaps
The Internet of Things (IoT) is growing at an extraordinary pace, with the number of connected devices expected to hit 41.6 billion by 2025. However, this surge has also created a massive attack surface. IoT devices face an average of 5,400 attacks per month, and successful breaches can cost organizations around $330,000 per incident. Key vulnerabilities include:
| Vulnerability Type | Consequence | Risk Level |
|---|---|---|
| Default Credentials | Unauthorized network access | Critical |
| Insufficient Encryption | Data interception | High |
| Weak Authentication | Device compromise | Critical |
| Outdated Firmware | Remote code execution | High |
Kaspersky researchers have observed:
"Although we cannot provide a precise estimate of the number of IoT vendors or products impacted, potentially millions of devices across various industries could be affected."
The risks don’t stop with IoT. Cloud-based infrastructures introduce their own set of vulnerabilities, further complicating the telecom security landscape.
Cloud Network Risks
Telecommunications was the most targeted industry in 2023, accounting for 38% of all tracked cyberattacks. A staggering 82% of these breaches involved cloud-stored data, with an average financial impact of $4.45 million per incident.
In April 2025, researchers at Fortinet uncovered a method that allowed attackers to maintain read-only access to vulnerable FortiGate devices, even after patches were applied. As Bruce Schneier points out:
"Audit helps ensure that people don’t abuse positions of trust."
Open RAN (Radio Access Network) architectures also introduce unique risks. The National Security Agency and the Cybersecurity and Infrastructure Security Agency caution:
"By nature, an open ecosystem that involves a disaggregated multivendor environment requires specific focus on changes to the threat surface area at the interfaces between technologies integrated via the architecture."
Recent incidents underscore the severity of these risks. In November 2024, the Salt Typhoon group breached major U.S. telecom providers, gaining access to sensitive data like call records, unencrypted messages, and audio communications from government officials. Just a month later, in December 2024, Chinese hackers infiltrated U.S. Treasury systems by exploiting vulnerabilities in a third-party vendor, BeyondTrust.
Nation-State Attack Methods
Nation-state actors are employing increasingly sophisticated techniques to infiltrate telecom networks, with methods becoming more destructive over time. Recent data highlights a 74% rise in direct intrusions exploiting technical vulnerabilities in software.
Data Capture Techniques
A striking example of these tactics is the Chinese state-sponsored group Salt Typhoon, which breached nine U.S. telecom providers. They gained access to sensitive data, including call records, unencrypted messages, and audio communications.
"We can’t accept this level of espionage on our networks. If you had 50 spies or contractors from the Chinese Ministry of State Security sitting inside a major telecom company’s building, they would be walked out and it would be a full-scale effort. That’s in broad strokes what has happened, but the access was digital."
– Laura Galante, former leader of the Cyber Threat Intelligence Integration Center
These breaches often serve as a gateway for deeper intrusions, leveraging technical exploits to expand their reach.
Network Access Methods
Exploiting technical vulnerabilities is a core strategy for nation-state actors seeking unauthorized access. For instance, in 2023, the group Storm-0558 used spoofed tokens to compromise Microsoft 365 accounts, impacting U.S. government departments. Meanwhile, malicious threats targeting open-source repositories have surged by 1,300% since 2020.
Key targets for these attacks include:
- Identity management systems
- Network edge devices
- Open-source technologies
- VPN gateways
- Administrative interfaces
These attacks don’t stop at network breaches; state actors are also directing their efforts toward critical infrastructure.
Infrastructure Attacks
The merging of IT and OT (Operational Technology) systems has created new vulnerabilities that attackers are quick to exploit.
"The interconnection between IT and OT systems creates a perfect vulnerability storm. Telecommunications providers must develop specialised capabilities that address both technological domains simultaneously."
– Dr. Raymond Chen, Director of Critical Infrastructure Protection at the National Cybersecurity Centre
In late 2024, Salt Typhoon demonstrated this by infiltrating U.S. telecom systems to monitor real-time communications involving prominent American politicians. This highlights how cyber intrusions are increasingly tied to political intelligence objectives.
"For years, America’s intelligence chiefs have warned Congress of critical infrastructure vulnerabilities… Chinese cyber forces quietly occupy positions inside American telecommunications, transportation, water, power, and defense manufacturing systems – ready to unleash devastating disruptions designed explicitly to shake American resolve during a crisis over Taiwan."
– Josh Steinman, CEO of Galvanick
These methods underscore a larger strategy aimed at weakening telecom security through surveillance and disruption, posing significant risks to national stability.

Protection Against State-Level Attacks
The telecommunications industry saw a staggering 94% rise in weekly cyberattacks during Q1 2025, averaging 2,664 attacks per organization. Tackling these threats requires a robust combination of protection, detection, and response protocols.
Core Security Measures
Securing telecom networks calls for a multi-layered approach. With 90% of internet traffic now encrypted, implementing TLS 1.3 is crucial – yet 44% of organizations face challenges in deploying it.
Key measures to strengthen security include:
- Certified cryptographic authentication to block identity spoofing
- Voice biometrics to detect AI-driven deepfake communications
- Network separation and segmentation to limit attack spread
- Frequent security assessments and timely patch management
These steps form the foundation for identifying vulnerabilities and responding swiftly to threats.
Threat Detection Systems
Effective threat detection relies on integrating advanced tools and strategies. Here’s a breakdown of essential detection components:
| Detection Component | Primary Function | Implementation Priority |
|---|---|---|
| SIEM Integration | Real-time threat monitoring and correlation | Critical |
| Behavior Analytics | Pattern analysis and anomaly detection | High |
| AI-Based Detection | Automated threat identification | High |
| Encrypted Traffic Analysis | TLS fingerprinting and monitoring | Medium |
Organizations need comprehensive monitoring systems targeting critical network points. Establishing baseline behaviors and configuring security appliances to flag unusual activities is essential.
"uses signature and non-signature-based methods such as machine learning and behavioral analytics to identify threats and malicious activities on the network and respond to them." – Fidelis Network Detection and Response Buyer’s Guide 2025
Attack Response Protocol
Detection is just the first step – responding effectively is equally critical. A solid response protocol should include:
- Quick threat identification to minimize damage
- Isolation of affected systems to contain the attack
- Rapid restoration of services to reduce downtime
- Detailed incident recording for analysis and future prevention
Organizations must establish an incident response team (CSIRT) with technical experts, infrastructure specialists, and management representatives. Regular simulations and drills are vital for ensuring readiness and uncovering weaknesses in the response plan.
The telecom industry also faces increased regulatory scrutiny, including mandatory annual security assessments and independent audits to ensure compliance with FCC cybersecurity standards. CEOs and CISOs are now directly accountable for certifying their organizations’ adherence to these stringent requirements.
While these measures aim to counter state-level threats, the challenge of mass surveillance through telecom networks remains a pressing concern.
Mass Surveillance Through Telecom Networks
State Control Through Surveillance
Governments around the world have long exploited telecom networks to conduct extensive surveillance. By taking advantage of vulnerabilities within these systems, they extend their ability to monitor and control communications on a massive scale. For example, in 2021, the U.S. government monitored the communications of 232,432 individuals, groups, and organizations under Section 702 of the Foreign Intelligence Surveillance Act. This same program previously captured over 250 million internet communications.
Many nations have developed advanced systems specifically designed to monitor telecom networks. Here’s a breakdown of some major surveillance initiatives:
| Country | Surveillance System | Capabilities |
|---|---|---|
| China | Golden Shield Project | Censorship, biometric tracking, and social monitoring |
| Russia | SORM | Real-time monitoring of internet and phone activities |
| India | Central Monitoring System | Interception of calls, emails, texts, and social media content |
| UK | Mastering the Internet (MTI) | Collection of email content and web browsing history |
These systems often rely on advanced persistent threat (APT) tactics, allowing governments to maintain long-term access to telecom networks.
"What China does is they use those sets of localized U.S. IP address edge devices to obfuscate the last couple miles of network traffic that is coming out of China. They very much understand that our authorities are much harder to use once you’ve jumped to U.S. IP space."
– Laura Galante, former leader of the Cyber Threat Intelligence Integration Center
The lines between state-sponsored surveillance and cybercrime have also blurred, as collaborations between governments and criminal networks become increasingly common. These developments paint a concerning picture of a world where state control is deeply entrenched and ever-expanding.
Modern Parallels to Orwellian Themes
The level of surveillance in modern telecom networks draws striking comparisons to the dystopian world described in 1984. A recent example is the 2023 Storm-0558 breach, where Chinese operatives accessed thousands of emails from U.S. government officials by compromising Microsoft 365 accounts. Senator Mark Warner called it "the most serious telecom hack in our nation’s history".
Surveillance has evolved from basic intelligence gathering to include destructive cyberattacks, with artificial intelligence now playing a key role in these operations. This has made state-sponsored surveillance not only more advanced but also harder to detect.
Governments worldwide have also embraced biological data collection as part of their surveillance strategies. For instance, in 2003, Australia issued 75% more wiretap warrants than the United States, with a per capita rate 26 times higher. Meanwhile, the UK’s National DNA Database, which holds samples from 5.2% of the population, demonstrates how biological data is increasingly tied to digital surveillance systems.
Conclusion: Building Stronger Telecom Defenses
The telecommunications industry is facing an increasingly hostile environment as state-sponsored cyberattacks become more frequent and sophisticated. To address these challenges, telecom providers must prioritize a multi-layered defense strategy that blends cutting-edge technology with stringent security protocols.
Recent incidents highlight the devastating consequences of such attacks. For example, in 2023, a state-sponsored operation disrupted Kyivstar‘s network, affecting 24 million users. This serves as a stark reminder of the vulnerabilities within critical telecom infrastructure and the need for proactive measures to safeguard it.
To strengthen defenses, organizations should focus on key areas of cybersecurity:
| Defense Layer | Implementation | Impact |
|---|---|---|
| Network Visibility | Enhanced monitoring and real-time analysis | Enables early detection of potential threats |
| Access Control | Zero Trust Architecture and multi-factor authentication | Reduces unauthorized access and strengthens security |
| AI Integration | AI-driven threat detection and automated response | Speeds up threat identification and mitigation |
| Supply Chain Security | Rigorous vendor vetting and continuous monitoring | Lowers risks from vulnerabilities in third-party systems |
A case in point is Portugal’s NOS, which successfully bolstered its cybersecurity defenses by using Censys for asset analysis and threat detection. According to Diogo Gonçalves, Cyber Defense Team Lead at NOS:
"With Censys, we assess risks within our domain and beyond, securing our partnerships and public cloud environments".
The importance of strengthening telecom defenses is further underscored by Anne Neuberger, Deputy National Security Advisor for Cyber and Emerging Technology, who noted:
"Communications of U.S. government officials ride on these private sector systems, which is why the Chinese were able to access the communications of some senior U.S. government and political officials. Until U.S. companies address the cybersecurity gaps, the Chinese are likely to maintain their access".
AI-driven security solutions are becoming essential for countering emerging threats, including deepfake attacks. It’s telling that nearly 90% of telecom companies now rely on AI for their security operations. This shift reflects a growing recognition of the role advanced technology plays in combating sophisticated cyber threats.
Regulatory frameworks like the EU’s NIS2 Directive and the U.S. FCC Cybersecurity Labeling Program are also steering the industry toward a "secure-by-design" mindset. These initiatives, combined with forward-looking security practices, are critical for fortifying telecom infrastructure against the constant evolution of cyber threats.
